Abstract
A dynamic mixer comprises a cylindrical chamber portion 50 the rear end of hich is closed by a sealing plate 51 provided with conical pipe sockets 58, 59 adapted for being directly inserted into outlet openings of cartridges from which the pasty components to be mixed are supplied. Due to the closed structure of the mixer housing 50, 51, contamination of the device by the components and cross-contamination between them is avoided when the mixer is removed from the cartridges. Further, the direct connection of the mixer to the cartridges results in minimum travelling distances for the components, thus low friction losses, which is particularly advantageous in case of substances of high-viscosity.
Claims4
A dynamic mixer comprising:
- a housing including a substantially cylindrical chamber portion defining a longitudinal axis and having front and rear ends,
- a sealing member for closing the rear end of said chamber portion, said sealing member having an interior surface, a central bore, and rearwardly projecting pipe means adapted for direct introduction into outlet openings of supply means containing components to be mixed,
- a discharge opening provided at the front end of said chamber portion for discharging a mixture formed from said components, and
- a mixer element disposed within said chamber portion and supported by said central bore for rotation about said longitudinal axis, said mixer element including wiper means for wiping the interior surface of said sealing member when said mixer element rotates, said wiper means having leading cutting edges for cutting up strands of said components as they enter said housing.
